COLLINGWOOD defender Tom Langdon has passed his final concussion test and is likely to line up in the Magpies' clash with old foe Carlton at the MCG on Sunday night.

 

Langdon was substituted out of last week's game in the third quarter against Hawthorn, after his head slammed into the MCG turf in a contest with opponent Jack Gunston.

 

The 20-year-old was restricted at training for much of this week but he managed to join in the full session on Friday morning and should take his place in the team against the Blues.

 

"It was probably a bit longer than I expected in terms of the recovery. I trained fully today and hopefully I'll be right to go," Langdon told AFL.com.au on Friday.

 

Langdon, one of the favourites to win this year's NAB AFL Rising Star Award, conceded he felt the affects of the serious head knock.

 

He has had one previous concussion at age 13, but nothing since.

 

"At the start of the week, my concentration and the headache symptoms were the biggest concern," Langdon said.

 

"I couldn't really focus on too many things. I ended up staying at home and watching TV for a few days and not really doing very much."

 

Concussion injuries continue to dominate the landscape following Jonathan Brown's retirement this week, along with the dramas surrounding Geelong's handling of Allen Christensen's head knock last Saturday evening.

 

But Langdon and the club are confident he has shaken off any ill effects.

Fellow defender Marley Williams has already been withdrawn from the Magpies' squad after injuring his ankle at training on Friday morning.

 

Williams has been replaced in the 25-man squad by youngster Ben Kennedy.
